Title: Inspection method for welded part of seam welded pipe
Inventor: MAEDA MINORU
IPC: B23K13/00
Filed: 1993-10-20
Abstract: PURPOSE:To correctly inspect welding quality by binarizing the image of a welded part, thinning the lines in a metal flow territory, and measuring the angle of metal flow. CONSTITUTION:The section of 9 welded part of a seam welded pipe A is photographed with a CCD camera 10. An image processing part 22 converts the original image of the camera 10 into a differential image, binarizes it, and outputs it to a first measuring part 24 and a second measuring part 26. The measuring part 24 thins lines in a metal flow territory so as to extract the center line based on the binarized image information of the processing part 22, measures the angle of the metal flow by computing the angle of the main axis of the center line against a decided direction, meanwhile the measuring part 26 measures the width of a melted layer based on the binarized image information of the processing part 22, and they are output together to a judging part 32. The judging part 32 examines whether the metal flow angle output from the measuring part 24 and the width of the melted layer output from the measuring part 26 are contained in the reference range stored in a memory part 28 or not, judges the welding quality of the welded part of the pipe A, and displays the judged results on a display device 40.

Title: Pixel circuit for driving liquid crystal
Inventor: MIKOSHIBA KEIMEI
IPC: G09G3/36
Filed: 1991-10-31
Abstract: PURPOSE:To decrease a leak current by reducing a voltage applied to a switching transistor(TR). CONSTITUTION:Depletion type TRs Q2 and W3 are connected on both sides of an enhancement type TR Q1 for switching, and the source-drain voltage of the Q1 is clamped with the source-gate voltages of the Q2 and Q3.

Title: Protection device for internal combustion engine
Inventor: YUGAWA HIDEKI
IPC: F02P11/02
Filed: 1985-12-20
Abstract: PURPOSE:To protect an operator against exposure to a danger due to a sudden engine stop by retarding ignition timing or causing a misfire for restricting the rotary speed of an internal combustion engine under a predetermined level when an abnormality detecting signal is occurring. CONSTITUTION:When the switch of a sensor 4 has closed due to the occurrence of an abnormal condition in the hydraulic pressure, the cooling water tempera ture and the like of an engine, PUTP1 is triggered and becomes electrically live. Consequently, an abnormality detecting signal is outputted through PUTP1. When the rotary speed of an engine has reached a value over a predetermined level in that condition, the output terminal of a comparator CM2 becomes non- earthed at every other ignition timing and a transistor TR4 becomes electrically live, thereby causing a short circuit between the gate cathodes of a thylister S1. Therefore, an ignition signal is not fed to the thylister S1 at every other ignition timing and ignition work is stopped, thereby making ignition sparks discontinuous. Consequently, the rotary speed of an engine drops and when said speed has fallen below a predetermined value, the output terminal of the capacitor CM2 comes to be kept in an earthed condition, thereby ensuring proper ignition work.

Title: Production of combustion catalyst
Inventor: YAMASHITA HISAO
IPC: B01J23/44
Filed: 1987-11-16
Abstract: PURPOSE:To obtain a heat resistant combustion catalyst to be used suitably for combustion at high temp. by mixing fine Pd powder prepd. to a specified particle size with a porous carrier. CONSTITUTION:A combustion catalyst is produced by mixing 0.1-5wt.% fine Pd powder prepd. previously to a particle size between 1000Angstrom  and 5000Angstrom  with a porous carrier comprising alumina, silica, etc. Since easily evaporable Pd having a small particle size is freed of the combustion catalyst produced by this method, the activity of the catalyst is not deteriorated even when the catalyst is used at high temp. for a long time. Accordingly, the catalyst is useful as a catalyst having high heat resistance suitable for combustion, particularly, at 800-1500 deg.C, thus effective utilization of Pd is attained.

Title: Semiconductor integrated circuit device
Inventor: YAMADA YUSUKE
IPC: H03F3/347
Filed: 1986-12-01
Abstract: PURPOSE:To make apparently the voltage-current converting characteristic of a transistor into a straight line by providing a transistor for converting a voltage-current and a differential amplifier, earthing the input edge of one side of the differential amplifier, combining other input edge to the input signal putting electrode of the transistor and connecting the output edge to the control electrode of the transistor. CONSTITUTION:The collector of a PNP transistor 9 is connected to the minus input terminal of a differential amplifier. For this reason, fot the differential amplifier, a negative feedback is applied from an output to a minus input, and the minus input terminal is controlled so as to come to be the same ground level as the base potential of the PNP transistor 8 with a negative feedback action. In this case, since the emitter potential of a multi-collector PNP transistor 13 is fixed to 0V, the fluctuation of the voltage between base emitters of the transistor 13 due to the fluctuation of the input signal is absorbed to the fluctuation of the collector potential of the transistor 9. Consequently, the characteristic of the collector current of the PNP transistor and the voltage between base emitters can be apparently made into a straight line and the distortion rate when the voltage signal is converted to a current signal can be significantly improved.

Title: Copying device
Inventor: USHIO MASARU
IPC: G03G21/14
Filed: 1998-10-09
Abstract: PROBLEM TO BE SOLVED: To enhance copying efficiency by making an image forming interval in the copying process of plural copies shorter than that in the copying process of one copy from the copying action of the first one copy. SOLUTION: The image reading actions of three original is are executed at an interval L1. Even when the plural sheets of recording paper exist in a carrying path leading to a resist roller from a recording paper starting part after the original is eliminated from an original supply table, the recording paper is not left in the carrying path when a copying action is finished because it is used in plural image forming processes like the copies C12, C22 and C32. Therefore, an image forming action can be executed at a paper supply interval L2, that means, the image forming interval being shorter than the image reading interval L1 being a rate-determining process regardless of it. Thus, the image forming action is executed at the short interval L2 from the first image forming action. As the result, a copying action is executed at a high speed.  In the copying process of the plural copies, the copying action is executed at the shorter image forming interval L2 from the first one copy without being restricted by the original reading interval L1.

IPC: B23B29/32
Filed: 1998-10-09
Abstract: PROBLEM TO BE SOLVED: To simplify a NC machining program by having a fixed tool mounting part whose center axis is arranged in parallel with the center axis of a rotary tool main spindle and arranging so that the turning index center line of a turret is nearly crossed with the center axis of the rotary tool main spindle. SOLUTION: When the work in the chuck of a first main spindle is machined by a rotary tool RT, a necessary milling operation is carried out by rotating and starring an X axis feed motor, Z axis feed motor and C axis motor. As the rotation center axis of the rotary tool RT (rotation center axis RC of rotary tool main spindle 40) is crossed with the turning index center line TC of a turrret 41, especially the preparation of a NC machining program for milling by the turning of a B axis is easy. In other words, as the center of the rotary tool RT only points to this direction, even if the turret 41 is rotated by an arbitrary angle or 180 deg., the preparation of the NC machining program is easy.
